EXHAUST GAS PURIFIER

摘要

An exhaust gas purifier in which regeneration control of a particulate filter can be carried out accurately by enhancing the temperature measurement accuracy of a temperature sensor. The exhaust gas purifier comprises a pair of dispersion plates (10, 11) having a large number of communicating holes (10a, 11a) disposed oppositely to the flow direction of an exhaust gas (3) in a filter case (7) which is provided in a position along an exhaust pipe (4), and a catalyst generation type particulate filter (6) contained in a containing chamber (12) defined by the dispersion plates (10, 11). The filter case (7) is provided with a temperature sensor (14) for sensing the exhaust gas temperature in the containing chamber (12), and a detector (15) of the temperature sensor (14) is located at a position where a flow of the exhaust gas (3) is formed.
